Using Docker with Azure Functions and SignalR Service

If you want to use Serverless Azure Functions and Azure SignalR Service with TaaS WebSocket/SignalR

Running TaaS with Azure Functions and Azure SignalR Service

Requirements

• Azure Account (https://azure.microsoft.com/en-us/free/)

• Docker

• Tezos Node with enabled RPC endpoint supporting following calls

  • /monitor/heads/main

  • /chains/main/blocks/hash

In this configuration we are using a different docker image - this one is only sending a new blocks to our Azure Function, which then sends parsed information to subscribers through Azure SignalR Service.

If you just want to use a Docker container without having to setup Azure infrastructure please check Using Docker documentation section.

Ready-to-use docker image is available from Docker Hub here: https://hub.docker.com/repository/docker/tezoslive/agileventurestezpusherconsoleapp

Example of the docker run command

• setting the Tezos:NodeUrl env. variable to https://172.17.0.1:8732

• setting the Azure:AzureFunctionUrl env. variable to https://myfunction.azurewebsites.net

• setting the Azure:AzureFunctionKey env. variable to MySecretFunctionKey

Be sure to configure the following ENV keys correctly per your environment

• Tezos:NodeUrl

• Azure:AzureFunctionUrl

• Azure:AzureFunctionKey

docker run -it --env Tezos:NodeUrl="https://172.17.0.1:8732" \
--env Azure:AzureFunctionUrl="https://myfunction.azurewebsites.net" \
--env Azure:AzureFunctionKey="MySecretFunctionKey" \
 tezoslive/agileventurestezpusherconsoleapp

This infrastructure setup has the following benefits

• It allows you to have a more robust security out of the box as all communication is encrypted by TLS.

• It makes scaling your applications for thousands of subscribers much easier by using serveless compute with scalable SignalR Service.
